Among the many articles, pamphlets, and booklets of all sorts seeking to explain how methadone maintenance treatment (MMT) really works, this book stands out most favorably. Edited by two experienced practitioners in the field - Mark Stanford, PhD, and Donald Avoy, MD - authors of the book's 8 chapters include such well-known clinicians as Joan Zweben, PhD, Judith Martin, MD, Robert Kahn, PhD, and others. The document was developed under the auspices of the Santa Clara Valley Health & Hospital System, Department of Alcohol & Drug Services (DADS), San Jose, CA. The text is easy to follow and all medical terms are clearly defined, so readers without medical training will find the book understandable. Yet, the authors do not shy away from what otherwise could be overly complex subjects.
